my Bujinkan video exploring 廻捕 mawashi dori with kunai. AKA Mawari Dori. I have studied both variations with Hatsumi Sensei, and there are subtle differences.
I began class with 廻捕 mawashi dori. This sometimes called mawari dori, and we did that later. But first, with 廻し mawashi, muto dori skill is critical. If you move too much, you give your opponent options to kill you. Collapse the space by receiving the attack.
